Octahedron Subgroups and Subrings [PDF]
Mathematics, 2020 In this paper, we define the notions of i-octahedron groupoid and i-OLI [resp., i-ORI and i-OI], and study some of their properties and give some examples. Also we deal with some properties for the image and the preimage of i-octahedron groupoids [resp.,

Arctic curves of the octahedron equation [PDF]
Journal of Physics A: Mathematical and Theoretical, 2014 We study the octahedron relation (also known as the $A_{\infty}$ $T$-system), obeyed in particular by the partition function for dimer coverings of the Aztec Diamond graph.

Distance and Similarity Measures for Octahedron Sets and Their Application to MCGDM Problems
Mathematics, 2020 In this paper, in order to apply the concept of octahedron sets to multi-criteria group decision-making problems, we define several similarity and distance measures for octahedron sets.

On multiplicative degree based topological indices for planar octahedron networks
Main Group Metal Chemistry, 2020 Chemical graph theory is a branch of graph theory in which a chemical compound is presented with a simple graph called a molecular graph. There are atomic bonds in the chemistry of the chemical atomic graph and edges. The graph is connected when there is

Mesoporous Octahedron-Shaped Tricobalt Tetroxide Nanoparticles for Photocatalytic Degradation of Toxic Dyes [PDF]
ACS Omega, 2020 The present article reports a facile approach to fabrication of mesoporous octahedron-shaped tricobalt tetroxide nanoparticles (Co3O4 NPs) with a very narrow size distribution for eco-friendly remediation of toxic dyes. Co3O4 NPs were fabricated by a sol–

A Periodicity Theorem for the Octahedron Recurrence [PDF]
Journal of Algebraic Combinatorics, 2006 We investigate a variant of the octahedron recurrence which lives in a 3-dimensional lattice contained in [0,n] x [0,m] x R. Generalizing results of David Speyer math.CO/0402452, we give an explicit non-recursive formula for the values of this recurrence in terms of perfect matchings.

Ramsey numbers in octahedron graphs
Discrete Mathematics, 2001 For \(t\)-colorings of the octahedron graph with \(2n\) vertices, \(O_n=K_{2n}-nK_2\), the octahedron Ramsey number \(r_O(G_1,\ldots,G_t)\) is defined as the smallest integer \(n\) such that any \(t\)-coloring of the edges of \(O_n\) contains a monochromatic copy of \(G_i\) for some color \(i\). Lower and upper bounds for octahedron Ramsey numbers with

On Topological Properties of Planar Octahedron Networks [PDF]
Polycyclic aromatic compounds (Print), 2022 In the research of QSAR and QSPR correlations, topological indices such as the Randi’c index, Zagreb index, ABC index, and geometric-arithmetic index have been proposed to analyze bio-compatibility of chemical compounds.

The Octahedron family as a source of tensegrity families: The X-Octahedron family
International Journal of Solids and Structures, 2020 Abstract A tensegrity family is a group of tensegrity structures that share a common connectivity pattern. The three first members of the Octahedron family are the octahedron, the expanded octahedron and the double-expanded octahedron. In this work a new family is presented: the X-Octahedron family.
